Extension of the frequency range up to 500 MHz for FRA and antenna analyzer modes
(homemade add-on)

The device in the FRA and AA modes can operate on the harmonics of the generator signal (software version 3.12 or higher). To obtain a high level of harmonics in the spectrum, you can use a rectangular pulse shaper made on a digital logic element of the LVC family. The fast slew rate of the ICs provides a high level of odd harmonics in the output signal even at high frequencies.
